Such a situation may indeed appear mature and responsible if it is carried out, but ultimately, when someone has become addicted to gambling, this situation—despite constant reminders—still leads them to act contrary to it at times because their ambition toward gambling is so high.
Several factors always serve as excuses in such situations, such as when they cross boundaries or unknowingly make mistakes like becoming too focused on the game, overly confident (when they win), and overly ambitious to recover losses (when they lose).
Yet it is clear that such situations require knowing when to stop and start again another day, and not being overly provoked by the game. This is a step that must be taken, but it is clearly filled with obstacles and not as easy as it seems.
Every gambling addict willing to recover from such a dangerous pathologic situation is in must need for support. He would definitely never succeed in overpass addiction without exterior interfer either from experts doctors but also from his closed family and friends. If you want to check medical process on how to help an addict, especially those suffering from behavioral addiction like gambling and masturbation, the process always require a psychological assistance usually provided within treatment facilities or by help of family members.
It can be a good move if there is support from outside parties such as family or doctors if we want to recover completely, because a person's mentality will be strengthened when there is a lot of support to help them get better quickly. However, on the other hand, it also depends on the gambler's own intentions. In some cases, even when someone is supported by family or professionals like psychiatrists or doctors for recovery, if the gambler lacks the intention to recover, then everything will seem the same, with no significant impact on progress. Therefore, the gambler's initial intention to stop is crucial in this regard.
This is a commun practice in every treatment for behavioral addicts. This kind of addiction pathology can't be treated with medicines only but it requires a full process behavioral treatment which all the environment should part of. The most important is that the patient himself should be aware of all of this.
